Hi my friends,

I am trying to sort curves stacked together and pick the ones I need to form enclosed rectangles.

The orange color marks to curves I want to extract and the red points are points I want to connect.
I wonder how to do it.

Thanks, Kim, yes, very cool, by using mesh shadow and sorting with z values.
